<p>Classes for management of all options used in the application and its plugins.</p>
<p>All options are described in <code>options.xml</code> under the <code>appdata</code> directory  
 and in <code>plugin.xml</code> under the root directory in the <code>plugin</code> directory for each plugin. 
 The <code>options.xml</code> file have following format:</p>
<pre>
	&lt;options&gt;
		&lt;optiongroup groupname="%groupname"&gt;
			&lt;option type="%type" name="%optionname" flag="%flag" default="%default" usage="%usage"&gt;
				&lt;desc&gt;%desc&lt;/desc&gt;
 				&lt;shortdesc&gt;%shortdesc&lt;/shortdesc&gt;
				&lt;legalvalue name="%legalvaluename" class="%class"&gt;%legalvaluedesc&lt;/legalvalue&gt;
				&lt;/option&gt;
			...
		&lt;/optiongroup&gt;
		...
	&lt;/options&gt;
</pre>
<p>One or many <code>optiongroup</code> elements are enclosed by the <code>options</code>. The <code>optiongroup</code> element
 enclose one or more <code>option</code>. Each option contains at least two description elements: <code>desc</code> and <code>shortdesc</code>.
 The attributes used by the <code>optiongroup</code> element and the <code>options</code> element are descibed below:</p>

 <p>An option of one the types: <code>enum</code>, <code>stringenum</code> and <code>class</code>, should at least contain one <code>legalvalue</code>
 element. Common for the three types is that they should contain an identifier specified by the <code>name</code> attribute and a short description of the
 legal value. For the <code>stringenum</code> type there should also be a <code>mapto</code> element that specifies what the identifier should be mapped to.
 The <code>class</code> type should contain a <code>class</code> attribute that specifies what class should be loaded.</p>
 
 <p>All options are described in a <a href="../../../../../options.html" target="_top">short version</a> and a <a href="../../../../../optiondesc.html" target="_top">long version</a>.
 The option value can be specified in different ways (see the user guide: <a href="../../../../../userguide.html#control" target="_top">Controlling MaltParser</a>.</p>
